Platform and integration support
Distinguish available artifacts from combinations validated on real machines.

Available artifacts
| Platform | Desktop | Edge CLI and hooks | Operator CLI |
|---|---|---|---|
| macOS Apple Silicon | .dmg | Available | Available |
| macOS Intel | No Intel desktop artifact | Available | Available |
| Windows x64 | .exe installer | Available | Available |
| Windows ARM64 | x64 desktop under emulation; no native ARM64 installer | Native ARM64 CLI | Native ARM64 CLI |
| Linux x64 / ARM64 | No desktop artifact | Released x64 / ARM64 archives | Available |
The reviewed public releases are CLI 0.13.6 and desktop 0.1.62 (September 16, 2026). Newer source code is not automatically part of either release. Linux has no desktop app or packaged systemd service; its hooks and MCP clients run without the desktop daemon.
Download Edge or use the installation guide. The desktop and standalone CLI release channels have different signing properties. Check the selected artifact; do not assume that a signed desktop installer implies every standalone archive is signed.
Agent coverage
Kastra has hook integrations for Claude Code, Codex CLI, Cursor, OpenClaw, and Hermes. A supported hook implementation is not proof that every agent version and operating-system combination was tested.
The recorded Windows hook validation covers Claude Code on Windows 11 ARM64. Windows Cursor and Codex hook execution remain unvalidated in that record. Windows daemon lifecycle has a separate x64 validation; it does not validate those agents. Validate your own combination before relying on enforcement.
Windows shell names
Use hook version 0.12.5 or newer for canonical Windows shell normalization. The hook maps the Windows shell spelling to Bash; older hooks may send a different name and miss a rule scoped to Bash. Combine the tool and OS attributes when you need a Windows-specific rule.
Hosted and source-only features
Hosted remote MCP has completed its security review; confirm workspace enablement and the actual server/client compatibility. The TypeScript SDK has an alpha implementation, but public npm installation is not verified. Source builds and feature branches do not establish public distribution support.
